Yea, i can't upgrade anymore on my Kindle Paperwhite 5.3.1... I was creating via PuTTy a filesystem but my Kindle made a reboot. After this i couldn't upgrade anymore. That means when i make a .bin file into /mnt/us/ directory and upgrade the Kindle under settings the display will be black and my KPW shutdown it self, so i have to press the power button for 7 seconds. If it restart then it comes the upgrade error 3. I can't also activate usbnetwork with ;un. When i start the usbnetwork.sh in kterm i get this error: '/usr/local/bin/usbnetwork.sh: /mnt/us/usbnet/etc/config: line 2: sysntax error: unexpected ")"'.

Thanks. So the update is NOT the problem (which is as it should be - I'd be very surprised if it was being sent out wirelessly yet. Amazon generally wait a while to see if any problems show up before they start automatic updates).
